Whether you rely on Windows Updates or third party software to update drivers, make sure you create a restore point (or better yet, a system image) in case the new driver causes issues.
Case in point: about a week ago Windows Update offered me a new Intel HD Graphics driver. I installed it and started experiencing error messages that Internet Explorer and/or Windows Explorer needed to close. I also got random BSODs for a Bad Pool Header.
Just because there's a new driver available doesn't mean it will make your computer perform better. When it comes to drivers I truly believe in the old saying, "If it ain't broke, don't fix it."
